TOP-PROP BLOCK.

SPECIFICATION forming part of Letters Patent No. 230,618, dated August 3, 1880.

Application filed April 9, 1880.

To all whom it may concern:

Be it known that I, LEONARD F. OURRIER, of the town of Salisbury, State of Massachusetts, havcinvented Improvements in Carriage- Top Props, of which the following is a specification.

This invention relates to the coverings of top-props of carriages; and it consists in a sleeve or tube, formed of rubber or other suitable elastic material, with a cylindrical interior or passage of a diameter to receive the Wooden body of the block, and with a corresponding exterior outline of cross-section, except that a longitudinal rib is formed thereon,

to serve as the cushion or bufl'er for the topbows when turned down.

Figure l is an endelevation of my improved covering. Fi 2 is a transverse section thereof, shown as mounted upon the interior wooden body or block. Fig. 3 is a longitudinal vertical section taken as on line Y Z, Fig. 2, but also showing the prop in elevation and in place in the block, the seatrail being shown in transverse section, and the top-joint eye, the inner washer, and cap-nut. all in vertical section.

In said drawings, a represents my improved covering, and I) is the longitudinal rib formed thereon. The wooden body is shown at c, in which is the axial passage (1, to receive the prop c, which extends from railf. The washer (No model.)

cility and at trifling cost, and the sleeve to may be advantageously cemented upon the body, or it can be stretched thereon so as to obviate danger of displacement. Y

By formin g covering a with a corresponding cylindrical interior and exterior, with the narrow rib I) raised upon such exterior, the sleeve may be thin, and consequently of good material, thereby producing a good article at small cost, the raised rib furnishing a sufficient cushion forthe bows.

I am aware that rubber coverin s for topprop blocks have been formed with a semicircular semi-oval exterior outline of cross-section, and with an interior passage or bore of a size to receive a body having a passage to receive the iron prop, such interior body being formed as a segment of a circle, and the passage in such covering corresponding thereto; and I make no claim to a covering so formed. Neither do I claim, broadly, or in the abstract, the rib b, as the same is of common use upon top-prop blocks formed entirely of rubber; but

What I do claim as my invention is- As an improved covcringi'or top-prop blocks, a sleeve of rubber having a circular interior wall or outline of a diameter to receive the body 0, and with a cylindric exterior, with the are-like rib b projecting therefrom, substantially as specified.

LEONARD F. OURRIER.
